8) Maintenance
Always disconnect power before servicing the system.
a) Lamp Maintenance
Most ultraviolet lamps are rated to provide 10,000 hours of continuous use. After 10,000 hours, the lamp
may no longer provide the sufficient amount of 254nm or 185nm that is required for UV output. Therefore,
the lamps need to be replaced on a yearly basis. Lamp status should also be checked on a periodic basis by
inspecting the LEDs on the ECC.
It is best to always keep spare lamps available in case of emergency needs.
If it becomes necessary to clean the lamp due to dust or fingerprints, the lamps can be cleaned with either
denatured alcohol or a non-abrasive cleaner. Use cotton gloves and a clean cloth when cleaning the lamps.
Wait for lamps to cool before cleaning.
b) Quartz Sleeve Maintenance (
FRAGILE: Be careful when handling quartz sleeves! Always use
cotton gloves when handling.)
In order to ensure proper disinfection, the quartz sleeves need to be inspected, monitored and maintained.
The UV lamps produce heat and UVC output, which may cause certain water characteristics to adhere to
and bond on the sleeve preventing the UVC from reaching the targeted pathogens. This can cause the quartz
sleeves to foul. To a great extent, your frequency of cleaning will depend upon the water quality (i.e. amount
of minerals present in the liquid). The more minerals present in the water, the more frequently the quartz
will require cleaning.
Manual Cleaning
Significant film or debris deposits formed on the quartz sleeves will impair the ability of the ultraviolet rays to
penetrate through the quartz and into the water.
A periodic visual inspection of the quartz will be necessary to determine the frequency of cleaning. Initial
inspection should take place after thirty (30) days of operation. If the quartz are dirty, shorten the cleaning
intervals. If the quartz are clean, lengthen the cleaning intervals.
To clean quartz sleeves, depressurize the unit by first turning off the valves on the inlet and then the outlet of
the vessel. Turn off the power to the UV system. Drain the vessel. Disconnect the lamps, allow to cool and
slowly and carefully remove the lamps using clean cotton gloves. Back off the compression quartz gland nuts
and remove the O-rings. The quartz sleeves may be cleaned with denatured alcohol. If this is not adequate,
a mild non-abrasive cleaner can be used. It is important to use cleaners that leave no residue.
FRAGILE:
Be careful when handling quartz. Whenever the quartz are cleaned, the quartz O-rings should be
replaced. Install the quartz sleeves with clean cotton gloves.
